Title: Improved method and apparatus for drawing glass tubes and canes
IPC: C03B15/14
Filed: 1932-11-21
Abstract: 391,060. Making glass tubing. CORNING GLASS WORKS, Walnut Street, Corning, New York, U.S.A.-(Assignees of Woods, W. J. ; 182, East 1st Street, Corning, New York, U.S.A.) Nov. 21, 1932, No. 32885. Convention date, Jan. 25. Addition to 354,509. [Class 56.] Relates to the method, described in the parent Specification, of drawing glass tubing in which the bore is backed by a coloured stripe. According to the present invention, the stripe is formed by guiding a closely-confined stream of contrasting glass into the root of the tube as it is drawn. The apparatus comprises a pot 24, housed in a furnace 13, which is divided into separate compartments 26, 27 by a transverse wall 25. An opening in the wall is controlled by an adjustable gate 32. A smaller pot 34, seated on blocks 33 in the compartment 27, is provided with a tapered nozzle 35, and the flow of glass through the nozzle is controlled by an adjustable gate 36. A refractory nipple 30, having a central opening 31, is inserted in the floor of the pot below the drawing-apparatus 22, and air can be blown through the opening from a pipe 39. In use, molten glass is deposited in the chamber 26, and molten glass of a contrasting colour is deposited in the pot 34. Glass flows from the chamber 26 into the chamber 27 and is drawn away as a continuous tube by the apparatus 22, air being blown through the opening 31 to maintain the bore of the tube. After the drawing is started, the gate 36 is raised to allow the contrasting glass to flow through the nozzle 35 into the root of the tube. The shape of the stripe thus formed is determined by the shape of the nozzle 35, and the position of the stripe in the tube is determined by the position of the nozzle.

Title: Digital data transmission system
IPC: H04M11/06
Filed: 1973-07-11
Abstract: 1437393 Digital data transmission, error correction WESTINGHOUSE ELECTRIC CORP 11 July 1973 [31 July 1972] 33024/73 Heading H4P A digital data transmission system comprises: a transmitter in which each data word to be transmitted is provided with a "field code" which identifies its position in a sequence of words; a receiver which temporarily stores and then retransmits the data; and means at the transmitter for comparing corresponding transmitted and retransmitted words to cause the transmitter to transmit again any incorrect data words. Data words to be transmitted are fed to register 71 where they are added to one of four sequentially repeated field codes representing the numbers 1, 2, 3, 4 and are then passed to an acoustic coupler for transmission over a telephone line. The register also feed the words to a two-word capacity store 73. At the receiver the received words are stored in register 84 and then returned to the transmitter and also passed to one of the two-word stores 90 or 91 depending on whether their field code is odd or even. The data words returned to the transmitter are compared in comparator 74 with the corresponding initially transmitted word and if they agree the next word is transmitted. If they differ, the word stored in register 73 is transmitted again and is again stored in receiver store 90 or 91. Thus if either store contains two words with the same field code, it indicates an error, and gate 92 is inhibited to prevent the incorrect word being fed to the output data buss. When two different words are stored, gate 92 is enabled to pass the first one to the output buss.

Title: Improvements in apparatus for gravity separation of granular material
IPC: B03B13/00
Filed: 1939-12-30
Abstract: 538,400. Separating coal, ores &c. HIRST, A. A., and SIMON-CARVES, Ltd. Dec. 30, 1939, Nos. 33091/39 and 15624/40. [Class 82 (ii)] In a method of separating granular materials such as coal or ores in a fluid suspension of intermediate specific gravity, the density in the separator is maintained by returning to the separator a mixture of thickened suspension and clarified liquid mixed automatically in the required proportions. In the plant shown the material to be separated is fed by a shoot 14 to a separator 7, which may be of the form described in Specifications 530,787 and 531,822, and the separated materials are drained on screens 19, 21, the suspension collected in the vessels 22 being passed to a tank 5 from which it is pumped back to the separator through a pipe 77. Dilute suspension resulting from spraying the products on the screens 19, 21 passes through pipes 27 to a tank 28 from which it is pumped to a thickener 30, thickened suspension from which is conditioned in a counter-balanced vessel 35 by agitating it with air supplied through a pipe 48. The size of the interchangeable nozzle 33 is such that the suspension passing therethrough is denser than that normally in the separator. If the density in the vessel 35 falls, the vessel rises, and its overflow passes to the tank 28, the same operation moving a flexible pipe 41 to direct the overflow from the thickener 30 through a pipe 47 to the tank 25 from which the sprays for the screens 19, 21 are supplied; if the density in the vessel 35 is sufficiently high its overflow passes to the tank 5. A float 64 in the vessel 5 operates a flexible pipe 59 to direct overflow from the thickener 30 either to the vessel 5 or to the tank 25; overflow from the thickener 30 also passes through a pipe 4 to the tank 25. In modifications, means are provided for automatically diverting to the tank 28 the flow of thickened suspension from the vessel 35 during the time clarified liquid is being admitted to the tank 5; or the admission of clarified liquid to the tank 5 may be controlled step-by-step through an arrangement of ratchets operated electromagnetically from the float 64; the float 64 instead of being in the vessel 5 may be in other positions such as at 105 or 106 in the separator 7, or in a pipe such as 77; and means may be provided for circulating the suspension within the tank 5.

Title: A process for stabilising phenol esters of aliphatic sulphonic acids
IPC: C07C303/44
Filed: 1961-09-19
Abstract: Phenol esters of aliphatic sulphonic acids (aliphatic radical of which is C10 to C20) which are used as plasticizers for nitrocellulose, chlorinated rubber and polyvinyl chloride are stabilized against oxidation and the action of light by incorporating in the plasticizer at least 0,1% by weight (based on the phenol ester) of compounds containing an epoxide group. The epoxy compound preferably contain up to 30 carbon atoms and preferably contain more than one epoxide group.  Vegetable oils containing epoxide groups are mentioned.  The preferred epoxy compounds are diglycide ethers of 2,2-bis-(4-hydroxyphenyl) propane, of ethylene glycol and of butane-1,4-diol and trimethylol propane diepoxide and trimethylol triepoxide.ALSO:Phenol esters of aliphatic sulphonic acids, the aliphatic radical of which contains 10 to 20 carbon atoms, are stabilised against oxidation and the action of light by adding to the ester at least 0,1% by weight (calculated on the weight of the ester) of a compound containing at least one epoxide group.  The phenol esters (i.e. phenol, cresols and mixtures thereof) can be obtained by treating industrial mixtures of aliphatic hydrocarbons containing from 10 to 20 carbon atoms (e.g. those present in coke-gas benzine) with sulphur dioxide and chlorine under the action of light and reacting the products with phenols in the presence of acid binding agents.  The epoxy compounds preferably contain up to 30 carbon atoms and preferably contain several epoxide groups.  Vegetable oils containing epoxide groups are mentioned.  The preferred compounds containing the epoxide groups are the diglycide ethers of 2,2-bis-(4-hydroxyphenyl)-propane, of ethylene glycol and of butane-1,4-diol and trimethylol propane diepoxide and trimethylol propane triepoxide.  In Example (1) the products obtained from the reaction of sulphur dioxide on coke-gas benzine are reacted with a mixture of phenols and cresols.  100 parts by weight of the ester has added to it 0,5 parts by weight of the diglycide ether of 2,2-bis-(4-hydroxyphenyl)-propane.  This mixture is exposed to U.V. light for 20 hours and then stored at 60 DEG C. in a drying chamber. Table I gives a list of the epoxide containing compounds used in similar experiments and includes epoxidised soya oil, lauryl glycide ether, phenoxy propene-2-oxide; isododecyl phenoxypropene oxide. Example (2) describes similar experiments involving different exposure times and storage times. The esters are useful as plasticisers for nitro cellulose, chlorinated rubber and polyvinyl chloride (see Group IV(a)).
